There are tons of posts on this subject. You may actually lose performance by removing the Cat in the headpipe (a couple of horse). You will have a bike that runs cooler and is louder. Replacing the headpipe with V&H True duals and Moster Ovals cost me a little under $1000. I did the work myself. Sounds great! Heat will kill an aircooled engine, IMO.
The dealer will honor warrenty on a lot of stuff if you bring it back to that dealer, if you are out of area when problem occurs you are SOL. you will have to get it back on your own.
Sorry for semi-necro'ing this thread but it seems the closest to the question i wanted to ask.. and didn't want to be the guy who doesn't search for an answer before asking questions.
So I now understand that my '10 RKC has the cat in the header pipe.. I assume that reduces the performance gain of just adding new slip-on's rather than the whole pipe? Are slip-on's still viable if i leave the cat in the head pipe? (still much cheaper which I like). I would be doing stage 1 AC and EFI remap at the same time of course.
Also if anyone has a ballpark of what I could expect to pay have this done? Most likely at an indy.. I know the rinehart slipons i was looking at run about $500.. dont know about the rest..
Thanks in advance for the help..
I ran my 2010 Road King with stock pipes for 10,000 miles without issue. Heat wasn't a problem and it ran fine. I was more interested in riding than upgrading.
About 1000 miles ago I had the stage 1 download done. I added the A/C, and put some Bub 7 Stealths on. The bike runs great. The Road King runs cooler than my Superglide and the Superglide had full pipes, SERT, A/C and a tune.
Download was around $150.00
A/C was +/- $139.00
Bub 7 Stealths were just under $500.00
Had my stage 1 done at the dealer after they uncrated the bike, and they are honoring the HD warranty as well as the warranty for the Dresser Duals and M/O and their dyno tune.
